CHARLES M. HINE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO J UDSON M. BEMIS AND STEPHEN A. BEMIS, OF SAME PLACE.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,414, dated April 19, 1881.

Application filed September 18, 1880. (No model.)

To all whom it may concern Be it known that I, CHARLES M. HINE, of St. Louis, Missouri, have made a new and useful Improvementin Sewin g-Machines, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, making part of this specification, in which- Figure l is a view in perspective, showing that portion of the sewing-machine with which the improvement is immediately connected; and Figs. 2 to 9, inclusive, views of the hook, showing it as it appears at various points in its rotation, Figs. 2, 4, 6, 8 being in front elevation, and Figs. 3, 5, 7, 9 being in side eleva-' two.

The same letters denote the same parts. The present invention is an improvementin singlethread sewing -machines. such as the Willcox & Gibbs machine, and it relates especially to the hook that takes the thread from the needle.

To provide an inexpensive hook, readily made of wire or like material, without any corners or notches wherein the thread can catch or wear the hook, and one by means of which the thread can, by the continuous revolution of the book, be steadily and properly taken from the needle and cast off, is the aim of this improvement. Referring to the drawings, A represents the needle of a sewing-machine having the improved hook.

B represents the hook, held in the hook-shaft C. The hook is made from wire, having the 5 point I), coil b, and shank b as shown in the drawings. In Figs. 2 and 3 the hook is taking the thread from the needle. In Figs. 4, 5 the book has made aquarter-turn. In Figs. 6, V

7 it 'has made a half-turn, and in Figs. 8,9

a three-quarters turn, and is ready to release 40 the thread. The coil 12, in front elevation, is preferably not exactly circular, but is elongated in the direction 00 m, Fig. 2. The inner part,

b of the coil 1) is shaped as shown mainly to prevent any sharp bends in the hook and to aid in casting off the thread.

I am aware that semi-rotating hooks have been before used; but I claim none of these, as my device is confined to the continuouslyrevolving book, which, byits peculiar construction, will, in operation, take the loop of the thread on its point, carry it part way along its coil, and then, in the continued revolution of the hook, by its reverse action on the thread, cast ofi' the loop, the said hook all the while having a direct forward revolution on its axis.

I claim The revolving sewing-machine hook B, having the point I), coil b, shank b and inner part, 12 whereby, in a continuous revolution, the stitch or loop is taken on itsend, carried part way along, and then, by the reverse movement of the bent portion of the hook on the thread, is cast off at the proper moment, substantially as shown and described.
